Negotiations have entered an around-the-clock phase in an effort to get a new NAFTA agreement within days, with top political staff converging in Washington for meetings stretching into the night Tuesday and beyond.

Top officials in the office of Prime Minister Justin Trudeau flew down to join Foreign Affairs Minister Chrystia Freeland for talks at the U.S. trade building, and President Donald Trump's son-in-law Jared Kushner also made an appearance.

After a three-hour meeting with her U.S. counterpart Robert Lighthizer, Freeland emerged to announce that she was remaining in Washington for at least another day.

"At this point everyone is working 24-7," Freeland told reporters. "It's about sending each other proposals and being ready to respond to them ... We are going to be working hard late into the night based on some of the points that were raised today.

"We'll be back at it tomorrow."

The source of this flurry of activity is the political calendar, with a confluence of events about to hit: a legislative deadline next month for the current Republican-led Congress to vote on the deal, the Mexican presidential elections, a short-staffed U.S. trade team trying to shift its focus to Asia — and fresh news that Lighthizer is being sent to China for talks next week.

Four people briefed on the NAFTA developments said they see a deal being possible as early as this week, based on a variety of factors. For one thing, the talks are drawing the political heavy-hitters of each country.
